Hybrid cars are mostly parallel hybrids. Only the Chevy Volt comes to mind as a serial hybrid.

Chevy Volt was still a parallel hybrid. The gasoline engine was used for driving the wheels for highway cruise because it was more efficient. I think the range extender version of the BMW i3 was a pure serial hybrid though

Honda's recent hybrids (CR-V, Civic, Accord) are like this too. Mostly series, but the engine can directly drive the wheels via a single overdrive gear for better cruising efficiency.

Some hybrid buses are also serial hybrids.
